The RedMax actuators are a revolution for safety, fire and shut-off dampers,
VAV systems, ball valves, throttle valves and other motorized applications
for HVAC systems in chemical, pharmaceutical, industrial and offshore/onshore
plants, for use in Ex-areas zone 2 (gas) and zone 22 (dust).
Highest protection class (ATEX) and IP66 protection, small dimensions,
only 9,5 kg weight, universal functions and technical data, an integrated
heater guarantee safe operation even under difficult environmental
conditions. High quality brushless motors guarantee long life.
All actuators are programmable and adjustable on site. Special tools or
equipment are not required. Motor running times are selectable or
adjustable on site. The integrated universal power supply is self adaptable
to input voltages in the range of 24...240 VAC/DC. The actuators are
100 % overload protected.
...Max-...-F3 actuators are equipped with spring return fail safe function.
Additionally the ...Max-...-SF3 and ...-BF3 actuators are equipped with
2 integrated, potential free auxiliary switches each and ...Max-...-BF3
comes with an intrinsically safe trip circuit for connecting the ...Pro-TT-...
safety temperature trigger. Standard shaft connection is a double square
direct coupling with 16 × 16 mm.
Different accessories are available to adapt auxiliary switches, terminal
boxes or adaptions for ball valves and throttle valves and other armatures.

A) Self adjustment of angle of rotation:
Switch (S) into position 02, then push button (T) for minimum 3 seconds. The actuator
will drive into both end positions to be adjusted. LED indicates GREEN.
Adjustment time needs approx. 93 sec. (90 sec. “On”, 3 sec. “Off”). After that, switch
(S) into the position acc. with your required torque and running time.
B) Selection of running time and torque:
Put switch (S) into the correct selected position in acc. to above table.
The selected parameter will work at next operation of the actuator.
Adjustment can be done even without supply voltage. If supply voltage
is available turn switch only if actuator is not running.
C) Function of the ExPro-TT-... in the Ex-i circuit:
If the sensor opens the Ex-i circuit the actuator runs into its safety end-position with
spring return.
D) Additional information for control mode:
a closed = actuator goes ON
a open = spring return mode
The rotation direction depends on left/right mounting of the actuator to the
damper/valve.

All actuators are equipped with a universal supply unit working at a voltage range from
24...240 VAC/DC. The supply unit is self adjusting to the connected voltage!
The safety operation of the spring return function works if the supply voltage is cut or
line 3 opened.
For electrical connection inside hazardous areas a terminal box is required (e.g. RedBox).
An over-current protection fuse < 10 A has to be provided by installer.
Note: The initial current is appr. 2 A for 1 second.
Supply at auxiliary switches must be the
same as supply of actuator and on same
fuse in case of power is switched.

RedMax-...-F3 RedMax-...-SF3 RedMax-...-BF3
Special option ... -CTM
Important information for installation and operation
Accessory RedBox – adaptable terminal boxAccessory RedSwitch – adaptable auxiliary switch
For electrical connection of ...Max actuators inside the
hazardous area a terminal box is required.
RedBoxes are appropriate terminal boxes and placed at
the disposal. To adapt the ...Box directly to the actuator
housing a mounting bracket type MKK-M is required.
RedBox- 3P for ...Max-...-F3
RedBox- Y/S for ...Max-...-SF3
RedBox- BF for ...Max-...-BF3
For an end or inclined position indication it is possible to
retrofit external, adjustable, explosion proof auxiliary switches
type RedSwitch. The switch housing is mounted directly to
the actuator and the switches are linked to the actuator’s
square connector. The switches deliver a potential free
output and can be adjusted separately. They are connected
by the included cable tail.
Extra information (see additional data sheet)
Additional technical information, dimensions, installation instruction, illustration
and failure indication
A. Installation, commissioning, maintenance
All national and international standards, rules and regulations for hazardous Ex-areas
must be complied. Certified apparatus must be installed in accordance with manufacturer
instructions. If the equipment is used in a manner not specified by the manufacturer, the
safety protection provided by the equipment may be impaired. For electrical installations
design, selection and erection, EN/IEC 60079-14 can be used.
For electrical connection an Ex-e terminal box is required (e.g. RedBox-...).
Attention: If the actuator is put out of operation all Ex rules and regulationsmust be
applied. You have to cut the supply voltage before opening the terminal box !
The cablesof the actuator must be installed in a fixed position and protected against
mechanical and thermical damage. Connect potential earth. Avoid temperature transfer
from armature to actuator! Close all openings with min. IP66.
For outdoor installation a protective weather shield against sun, rain and snow should be
applied to the actuator as well as a constant supply at terminal 1 and 2 for the integral
heater.
Actuators are maintenance free. An annual inspection is recommended. For electrical
installations inspection and maintenance, EN/IEC 60079-17 can be used. Ex-actuators
must not be opened by the customer.
B. Manual override
Manual override only if supply voltage is cut. Use delivered socket wrench with slow
motions, usage can be tight.
Attention: Releasing or letting go the Allen key too fast at manual operating actuators
with spring return causes risk of injury!
C. Shaft connection, selection of running time
Actuators are equipped with a direct coupling double square shaft connection of 16 × 16 mm.
The housing of the actuator is axially symmetrically built to select Open-close direction
of the spring return function by left-right mounting. Using the 10-position switch different
motor running times and spring return running times can be selected on site in acc. to
the actuator type.
D. Temperature trigger ...Pro-TT-...
The actuator ...Max-...-BF3 will work only with the temperature trigger ExPro-TT-...
E. Spring return
Spring return function works only if the supply voltage for terminal 1 or 2 is cut. In the
event of an electrical interruption, the spring returns to its end position even if supply
voltage is available again during return function. Thereafter operation will continue.
F. Operation at ambient temperatures below −20 °C
All actuators are equipped with a regulated integrated heating device designed for
employments down to −40 °C ambient temperature. The heater will be supplied automatically
by connecting the constant voltage supply on the clamps 1 and 2.
1. After mounting the actuator must bei immediately electrically connected.
2. The heater switches on automatically when actuator reaches internally −20 °C. It
heats up the actuator to a proper working temperature, then heater switches off au-
tomatically. Actuator will not run during heating process.
3. The adjustment options are only ensured after this heating up period.
G. Excess temperatures
In acc. to the ATEX rules and regulations Ex actuators must be protected against excess
temperature. The internal thermostat works as a maximum limiter and, in the event of
failure at incorrect temperatures, shuts off the actuator irreversible. An upstream connected
temperature sensor stops the actuator before reaching its max. temperature. This safety
feature is reversible, after cooling down the actuator is completely functional again. In
this case the failure must be eliminated immediately on site!
H. Synchron mode
Do not connect several actuators to one shaft or link mechanically together.
I. Mechanical protection
The actuator must be operated with an outside load of at least 10 Nm.
After installing the actuator to the damper/armature an automatic alignment has to be ac-
complished in order to obtain a “gentle” blockade/stop. This function protects the
damper/armature by reducing the end position’s/blockade speed in order to avoid
mechanical overload. The actuator alignes specifically once with 90 s/90° onto each
position and recognizes the blockade position in order to reduce the motor performance
during operation briefly before reaching the end/blockade position.
J. Intrinsically safe circuits
The supply of the push button (adjustment drive), the 10-position switch (adjustment of
torque and running time), the LED indicator and the sensor connection ExPro-TT is
performed intrinsically safe!
K. Routine tests of fire dampers
For periodic inspection of fire dampers cut off the supply line (current of actuator).
The test button at ExPro-TT-... is only for test aims of actuator’s function.
